In the Spring and Autumn Period, a farmer in the State of Song was one day working in the fields when he saw a rabbit bump into a tree stump（树桩） accidentally and break its neck. The farmer took the rabbit home, and cooked himself a delicious meal. That night he thought, 'I needn't work so hard. All I have to do is wait for a rabbit each day by the stump.' So from then on he gave up farming, and simply sat by the stump waiting for rabbits to come and run into it.
This idiom satirizes（讽刺，挖苦） those who just wait for a stroke of luck, rather than making efforts to obtain what they need.
守株待兔
宋国有个农夫正在田里翻土。突然，他看见有一只野兔从旁边的草丛里慌慌张张地窜出来，一头撞在田边的树墩子上，便倒在那儿一动也不动了。农民走过去一看：兔子死了。因为它奔跑的速度太快，把脖子都撞折（shé）了。农民高兴极了，他一点力气没花，就白捡了一只又肥又大的野兔。他心想；要是天天都能捡到野兔，日子就好过了。从此，他再也不肯出力气种地了。每天，他把锄头放在身边，就躺在树墩子跟前，等待着第二只、第三只野兔自己撞到这树墩子上来。世上哪有那么多便宜事啊。农民当然没有再捡到撞死的野兔，而他的田地却荒芜了。
这个成语用来讽刺那些坐等机遇的人，而不是通过努力而获取他们的所需。
